Hi,

Since some time, all of my Aeotec Multisensors 6 don’t measure ultraviolet (UVI) anymore. The property is still visable in the Homey App and also in MQTT but the measurement is always 0. It worked before, however I can not pinpoint the moment it stopped working. All other measurements work fine.

I already have:

- Removed and added the devce
- Uninstalled / Installed the app
- Resetted Homey
- Changed batteries

Athom Support has no idea what can cause this. Anybody had the same issue or any suggestions on how to solve this?

Thanks,  
Ron

Thanks!  
I have tried it with USB powered the sensor. Still no readings. Meanwhile I have asked Aeotec support for help and they responded immediatly, so that was a positive experience. However, no solution yet. They did confirm thevalue should be readable through Homey, so I think I will have to experiment a bit more.

Thanks for the suggestion.
